Spray 10" x 10" pan with nonstick baking spray and place strips of parchment paper in bottom of pan so the parchment extends over the four pan sides. (note: a 9" x 13" pan may also be used)
In a medium bowl, whisk together flour, ginger, cinnamon, baking soda and salt. Set aside.
Using a stand mixer with the paddle attachment, begin creaming the butter and granulated sugar until light and fluffy (2 - 4 minutes on medium speed). Scrape the bowl as needed.
Add the egg and molasses to the bowl and mix on medium speed until incorporated. Scrape the bowl as needed.
Add the flour mixture and mix on low speed until combined.
Pour the dough into the bottom of the prepared pan. Using your hands, lightly press the dough down so it evenly covers the bottom of the pan.
Bake for 15 minutes. Note: crust will be partially baked; it will finish baking after the Pumpkin Cheesecake topping is added to the pan.
Let cool before making the Pumpkin Cheesecake topping.
Make Pumpkin Cheesecake Topping
Place cream cheese in the bowl of a stand mixer fitted with the paddle attachment. Run mixer on medium speed for one minute. Scrape down the sides of the bowl and mix on medium speed for another minute.
Add granulated sugar and mix on medium speed for 2 minutes.
Add eggs and egg yolk one at a time, mixing between each addition.
Add pumpkin puree and spices. Mix until fully incorporated, scraping the sides of the bowl as needed.
Pour Pumpkin Cheesecake topping over the partially cooked ginger cookie crust. Spread mixture evenly.
Bake and Unmold

Cool at room temperature for one hour. Place in refrigerator for 2 hours to set completely.
Unmold by pulling up on sides of parchment paper and transfer to a cutting board. Remove parchment from bottom of the bar. Cut into desired shapes.
